Investigation of Sequential Cryogenic Hard Turning and Ball Burnishing Processes
K. Żak, W. Grzesik, M. Prażmowski, Opole University of Technology, Department of Manufacturing Engineering and Automation, Opole, Poland This paper presents a sequential machining process which incorporates CBN hard turning with cryogenic pre-cooling of the workpiece (CHT) and ball burnishing (BB). The main goal of this study was to select machining conditions enhancing the quality of parts mac...
متن کاملStudy of the lateral pass width for conventional and ultrasonic vibrations- assisted ball burnishing on Ti-6Al-4V specimens
Ball burnishing is a technological finishing process based on plastic deformation of the objective surface by means of a hard ball gliding over it. Along with its easiness of application, possible on the same machine where machining was performed [1], burnishing is a comprehensive process able to achieve surface roughness improvements, and compressive residual stresses up to deep layers of the ...
متن کاملExperimental characterization of the influence of lateral pass width on results of a ball burnishing operation
Ball burnishing has proved to be a highly effective mechanical finishing process of industrial workpieces, because of the excellent surface roughness and fatigue performance that induces in treated workpieces. In order to obtain specific target results from this complex plastic deformation process, its parameters must be accurately controlled. This paper focuses on the influence of the lateral ...
متن کاملDetermination of Surface Roughness by Ball Burnishing Process Using Factorial Techniques
Burnishing is a method of finishing and hardening machined parts by plastic deformation of the surface. Experimental work based on central composite second order rotatable design has been carried out on a lathe machine to establish the effects of ball burnishing parameters on the surface roughness of brass material. Analysis of the results by the analysis of variance technique and the F-test sh...
متن کاملVibration-assisted Compaction of Biomass
The biomass extrusion process for making biomass briquettes or logs normally requires large amounts of energy to overcome the springback of the material and friction with the die surface. Also, the products readily expand and disintegrate because of the retention of internal stresses. In this study, tests on vibration-assisted compaction of biomass were performed as a method to reduce the energ...
